Hello all, and welcome to a fairly successful OU team that I build a while back.
This team features Manaphy 
the Sea Guardian who can sweep with the correct set up.
I threw In Galvantula 
for speed drop support.
I desperately needed a Charizard counter, and Lenub recommended Landorus-T 
so I just went with that.
My team had trouble with Mega-Venusaur, and Gothitelle 
perfectly counters that.
I wanted a good strong Mega, so Mawille 
did the job for me
I needed a fire counter as well as a Rock setter, so I chose Heatran 
the most generic thing ever.

v5 @ Leftovers
Ability: Hydration
EVs: 202 HP / 56 SAtk / 252 Spd
Timid Nature
- Tail Glow
- Surf
- Ice Beam
- Energy Ball
Oh boy, this thing right here can sweep so many teams after threats are gone. A very generic set really, except I put HP EV's on to survive stuff, plus Tail Glow boosts my special attack insanely high anyways.
>252+ SpA Thundurus Thunderbolt vs. 202 HP / 0 SpD Manaphy: 314-372 (80.3 - 95.1%) -- guaranteed 2HKO after Leftovers recovery
Mr. Train @ Focus Sash
Ability: Compound Eyes
EVs: 252 SAtk / 4 SDef / 252 Spd
Timid Nature
- Hidden Power [Ice]
- Sticky Web
- Thunder
- Bug Buzz
I needed Sticky Web support Manaphy sweep to slow down enemy Pokemon who are faster, and Galvantula actually does stuff for my team and isn't a dead weight. I mainly abuse the Sash and use it as a comeback Pokemon. I considered using HP Fire over Ice to hit Excadrill, but I guess Lando was more important.
Cheekin @ Choice Scarf
Ability: Intimidate
EVs: 4 HP / 252 Atk / 252 Spd
Jolly Nature
- Stone Edge
- Earthquake
- Knock Off
- U-turn
I have to thank Leboss for this set. The ultimate Charizard check, Scarf outspeeds both variants and and OHKO's with Stone Edge or earthquake. It's been back and forth about Superpower or Knock off, and Knock off won by just a bit as Superpower only really hits Ferrothorn, as Knock Off is much more useful.
Nogare @ Choice Specs
Ability: Shadow Tag
EVs: 80 HP / 252 SAtk / 176 Spd
Modest Nature
- Psyshock
- Shadow Ball
- Energy Ball
- Hidden Power [Fire]
I had Zapdos in this slot (Which is why Zapdos is in that replay) but I desperately needed a Conkeldurr and MVenusaur counter, so I put in Gothitelle to trap and at most 2HKO both of them. 176 Speed outspeeds non-boosted base 86 (AKA: Rotom-W)
>252+ SpA Choice Specs Gothitelle Psyshock vs. 252 HP / 0 Def Mega Venusaur: 290-344 (79.6 - 94.5%) -- 43.8% chance to OHKO after Stealth Rock
>252+ SpA Choice Specs Gothitelle Psyshock vs. 252 HP / 252+ Def Mega Venusaur: 218-258 (59.8 - 70.8%) -- guaranteed 2HKO after Stealth Rock
JawMaster @ Mawilite
Ability: Intimidate
EVs: 236 HP / 252 Atk / 20 Spd
Adamant Nature
- Substitute
- Focus Punch
- Play Rough
- Sucker Punch
This thing demolishes anything and everything. SubPunch was my old Conkelfurr (stolen from MrK, sorry MrK x3) and frankly, it works on this as well. 20 Speed outspeeds base 16 Mawille's and other slow stuff. I chose Sub Punch > Sub and three moves because fighting + ghost covers just about everything, and Play Rough over Iron Head just because I don't want Azumarill kind of walling me.
Larvamob @ Leftovers
Ability: Flash Fire
EVs: 252 HP / 68 Def / 188 SDef
Calm Nature
- Roar
- Stealth Rock
- Lava Plume
- Earth Power
My main fire counter, and my specially defensive wall. Counters Volcarona, Zapdos, Venusuar to an extent, and friends. Pretty generic set, except specially defensive > physical just to counter special Aegislash.
